GAGE FOR PAPER-CUTTING MACHINES.

SPECFICATION forming part of Letters Patent No. 466,430, dated January5, 1892.

Application filed December 29, 1890. Serial No. 376,115. (No model.)

` of Kansas City, Jackson county, Missouri,

Vafter described and claimed.

have invented certain new and useful Improvements in MeasuringAttachments for Paper-Cutters, of which the following is a full, clear,and exact description, reference being vhad to the accompanyingdrawings, forming a part hereof.

My invention relates to appliances to be used as attachments to machinepaper-cutters; and the objects of my invention are to provide anattachment which shall be simple, durable, and comparatively inexpensivein construction, and which shall serve fo accurately gage the width orother dimensions into which the paper is to be cut, and Which shall,furthermore, be easily and quickly manipulated to vary the measurementsof the eut paper, and, finally, which shall be capable of readyattachment to and removal from paper-cutting machines of a great varietyof 'types To the above4 purposes my invention consists in certainpeculiar and novel features of construction and arrangement, as hereinlnorder that my invention may be fully understood, I will proceed todescribe 'it with reference to the accompanying drawings, in which-Figure 1 is a perspective view of a papercuttingv machine having myimproved gage applied thereto. Fig. 2 -is a central verticallongitudinal section of the bed of a papercutting machine and theimmediately adjacent parts with my improved gage applied thereto, thesaid figure being on an enlarged scale. Fig. 3 is a plan view of the bedof a paper-cutting machine with my improved gage applied thereto, thesaid figure being also on an enlarged scale. Fig-4 is a detachedperspective View of the graduated scale-sleeve. Fig. 5 is a detachedperspective view of the movable fence-bar. Fig. 6 comprises detachedperspective views of certain parts hereinafter described. Fig. 7 is atransverse vertical section of the gage 011 the line o; of Fig. 2.

In the said drawings, 17 designates the bed or base of a paper-cuttingmachine; 18, the usual fence-bar of the same; 20, the usualadjusting-screw rod of said bar, said rod eX- tending beneath the bed 17from front to rear thereof, and being reduced at its rear endv 23 topass through the pendent ange at the rear edge of the bed, the front endof the said adjusting-bar carrying the usual hand- A Yalsoth'e severalother parts above described,

such parts being shown to render the operation of my improved gageclear.

7 designates the body portion of the fencebar, said bar being ofelongated form and of such length as to extend from the front end of thebed of a press to or nearly to its cutting-knife, and being preferablyof rectangular form in cross-section, as shown. At its inner end thisbar is formed or provided with an upwardly-extending arm or fence 8.This fence bar is surrounded by an elongated sleeve 4, the upper side ofwhich is provided on its external surface with a scale 6, graduated tofeet, inches, and fractions of inches, one end of the sleeve having aring 5 passing therethrough. In assembling these two parts the ring 5 isfirst detached from the fence-bar 7, and said bar is pushed lengthwiseinto the sleeve 4, the ring 5 being then placed in position.

The bar 7 and Aits sleeve 4 are retained in operative relation by anysuitable numberA of set-screws 9, which pass upward through the underside of the sleeve, and the upper ends IOO the plate in position. Asetscrew 14: is in serted through a screw-threaded opening 15 in thebend of this guide, and the inner end of this set-screw impinges uponthe upper side of the friction or bearing. plate and presses the latteragainst thescale-sleeve, and thus retains the sleeve and bar in anyrequired position of adjustment, the bearingplate serving to preventmutilation of the graduated surface of the scale-sleeve by the inner endof the setscrew lll. The manner of using this gage is obvious, the knifeof the paper-cutter is raised and the pile` of paper to be cut. isplaced upon the bed of the machine. The set-screw 14 is now loosened andthe scale-sleeve and fenoe-bar are moved to the required distance in theguide l0, after which the set-screw let is tightened up. The pendentflange of the stop-piece is now brought against the front edge of thebend and the pile of paper is pressed against the fence 8 of said bar,and the cutting mechanism is operated in the usual manner to sever therequired portion of paper.

From this description it will be seen that the device is simple andinexpensive n construction, is readily adjusted for use, and is,furthermore, adapted for use in connection chines, dac., comprising astop-piece of substantially L shape in cross-section, and provided witha U-shaped guide upon the upper side of the stop-piece, a graduatedsleeve passing through said guide, a ring passing through one end ot'the said sleeve, a bearing-plate interposed between the upper surface ofthe sleeve and the under surface of the bend of the guide, a set-screwWorking through the bend of the guide and imping ing upon thebearing-plate, a fence-bar Work ing in said sleeve and having aprojecting arm or fence ab one end,and a number of setscrews passingthrough the sleeve andimpinging upon the bar, substantially as setforth.

In testimony whereof I afiix my signature in presence of two Witnesses.
